x86/fpu: Reorganize fpu/internal.h

Browse source

fpu/internal.h has grown organically, with not much high level structure,
which hurts its readability.

Organize the various definitions into 5 sections:

 - high level FPU state functions
 - FPU/CPU feature flag helpers
 - fpstate handling functions
 - FPU context switching helpers
 - misc helper functions

Other related changes:

 - Move MXCSR_DEFAULT to fpu/types.h.
 - drop the unused X87_FSW_ES define

No change in functionality.
